SIGNALING SYSTEM.

Specification of Letters Patent. Patented Dec. 23, 1913.

Application filed June 21, 1912. Serial No. 705,049.

To all whom it may concern: 1

of the United States of America, residing at Rolfe, in the county of Pocahontas and State of Iowa, have invented new and useful Improvements in Signaling Systems, of which the following is a specification.

My present invention 'relates to improvements in signaling systems or apparatus and has particular application to a sending or transmitting apparatus for such systems. I

wherein sounds may be transmitted from one point to another and high tension currents used to facilitate the tra'nsmission'of such sounds.

It is also my purpose to provide a signaling system wherein by means of an operat ing circuit, a signaling circuit may be en ergized to send out sounds, a novel form of circuit closer being employed in the signaling circuit and actuated from the operating circuit to close the former circuit.

Furthermore, I aim to provide a system of the above-stated character which shall include a circuit closer composed of a rotatable member provided with concentrically arranged conducting and non-conducting surfaces with which may be engaged a contact lever operable from the operating circuit of the system to close the signaling circuit.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the appended claims.

In the accompanying drawings; Figure 1 is a diagrammatic view of a signaling system embodying the present invention. Fig. 2 is a detail perspective view of the circuit closer, and Fig. 3 is a diagrammatic view of a modified form of the invention.

In the accompanying drawings I have shown my invention as applied to a wireless telephone system. Certain features of the invention, however, ar applicable to sigv vention to the best advantage according to Be it known that I, J GEN OLSEN, a citizen the circumstances or requirements in any particular case.

Similar reference characters designate like parts throughout the several views.

- Referring now to. the accompanying drawingsin detail, my improved signaling system includes an operating circuit A, composed in this instance, of a telephone transmitter 1, an induction coil 2 and the circuit f wires 3,-asuitable source of energy such as In carrying out this invention, it is my purpose to provide a system. of this type;

: The signaling circuit, in' the present instance, is composed of the two circuits so that high tension currents or currents of relatively high voltage may be transmitted to the'sparking device, thence to the aerial. Each-signaling circuit, in the present instance, comprises the conductors 6 and 7 conneoted to the primary circuit of a spark coil 8 and having one terminal connected to a binding post 9 of the circuit closer C, while the opposite terminal is connected to one pole of a suitable source of electrical energy such as a battery 10, the opposite pole of which latter is connected to one end of a lever of the circuit closer by way of a conductor 11. The secondary circuit-s of the spark coils 8, 8 are indicated by the numerals 12, 12 and terminate in a sparking device 13 embodying a rotary drum or cylinder 14, the latter having connection with an aerial 15 so that upon the energization of the secondary circuits of the spark coils 8, waves may radiate from the aerial.

In order to .close the signaling circuit from the operating circuit, I employ a circuit closer which is indicated as an entirety by the letter C. This circuit closer embodies a rotating drum or cylinder 16 composed, in this instance, of the two sections 17 and 18 insulated from each other by means of suitable insulating material designated at 19. These sections are preferably constructed of brass or other suitable conducting material and have their outer extremities circumferentially reduced to provide nipples 20, 20 about which is wrapped hard rubber 21 or the like non-conducting material, such material lying flush with the larger circumferences of the sections so as to present, in effect, a continuous cylindrical BEST AVAILABLE co surface] 'Irunnions 22, 22 are formed at the opposite ends of the cylinder 16 and are Wires 6 of the signaling circuit. The magnet of the operating circuit is also mounted upon this base and is disposed between a pair of contact levers 25, 25 each equipped with an armature'26 and pivoted to the base as'at 27, theiopposite or free ends of such levers terminating in bifurcated substantially attracted by the magnet 5 and consequently swing such levers about their pivotal connections 27- and bring thecontacts 28 onto the sections l7 and 18 ofat-he cylinder 16 wherebythe signaling circuit will be closed, the cessation of such sound permitting the contacts 28 to ride off of the conducting-sun. faces of the circuit closer and onto the nonconducting surfaces2l thereof, thus when a succession of sounds are directed into the transmitter, the contact 28 will be engaged alternately with the conducting and nonconducting surfaces of the circuit closer, a suitable form of motor being employed to drive the rotating drum of the circuit closer -:to facilitate the closing of the signaling circuit, the rotation of the circuit closing drum being-approximately synchronous with that of the sparking device.

In the modification of the device disclosed in Fig. 3, I make use of a motor -M connected in circuit with a suitable source of electrical energy and equipped with a driving shaft 29 geared to the drums 14: and 16 of the sparking device and circuit closer respectively. Leading from the motor are conductors 30 and 31 terminating in contacts 32, 32 fastened to the platform 34 of the circuit closer, one of such contacts being movable to engage the other and operable from one of the levers 25 of the circuit closer by means of a pin 33 so that upon energization of the magnet 5 from the operating circuit, the motor circuit may be closed to permit the operation of the motor and conse-' quently drive the sparking and circuit closing drums, a positive and synchronous movement being imparted to such drums journaled in bearing brackets 23, 23 mount ed upon a base or platform 24 and receiving the binding post 9 of the terminals of the from the motor.

While I have herein shown and described one embodiment of my invention, by way of illustration, it is to be understood that I do not confine myself to all of the details of construction herein set forth, as modification and variation may be made within the scope of the claims and without departing from the spirit of my invention.

I claim: a

1. A circuit closer comprising a rotating drum formed oftwo sections insulated from each other and composed ofeondueting material, ringsiof non-conducting material surrounding the free ends.- .of said sections, means for supporting said cylinder for rotation, a pair of contact levers each pivoted at one end and equipped with an armature and having its opposite or free end bifurcated to :iorm' substantially semicircular contacts designed to embrace the adjacent section of. the' cylinder-and normally resting lupon :the: respective insulated; 'ring, and means for swinging said levers to contact the bifurcated ends thereof with the conducting surfaces of the cylinder.

.2. A circuit closercomprising a rotating I drum formed of two sections insulatedfrom each other and composedof conducting material, rings ofnon-conducting material surrounding .the;free ends of said sections, .means for .supportingsaid cylinder for rotation, a pairofcontact levers each pivoted at :one end and equipped with an armature JOHN OLSEN.
